Years ago, only car stereo makers would advertise “2,000 Watts Of Earthshaking Power!” But with the recent shift to switching power supply amplifier topology, we’re now seeing this with many pro-oriented products.

What’s behind the hype? And what about properly matching power amplifiers and loudspeakers? Answers start by focusing on the fundamental unit of measure in audio, the watt.

In ” The Power Amplifier-Loudspeaker Relationship,” Chapter 2 of the new PSW Expert Series on the essentials of audio amplification, author John Murray clearly defines wattage and what it means in terms of powering professional loudspeakers. Topics he covers include:

  • Meaningful calculation of watts (Ohm’s Law)
  • Power handling capacity
  • Headroom standards
  • Short-term (instantaneous-peak) versus long-term ratings
